德國洛克進口液氧截止閥

一、進口液氧截止閥產(chǎn)品特點：

1、在低溫介質(zhì)下具有長時間工作的能力;

2、直接與低溫介質(zhì)接觸的組合件具有防爆和防火結(jié)構(gòu);

3、在低溫工作的材料要保證其低溫性能,以防止摩擦件擦傷;

4、在低溫及無油潤滑的情況下，具有良好的耐摩性。

1. It can work for a long time in low temperature medium;

2. The assembly directly contacting with low temperature medium has explosion-proof and fireproof structure;

3. The material working at low temperature should ensure its low temperature performance to prevent abrasion of friction parts;

4. It has good friction resistance at low temperature and without oil lubrication.

二、進口液氧截止閥設(shè)計要求:

1、閥門在低溫介質(zhì)及周圍環(huán)境溫度下應(yīng)具有長時間工作的能力。

2、低溫介質(zhì)不應(yīng)對手輪操作及填料密封性能產(chǎn)生有害的影響。

3、直接與低溫介質(zhì)接觸的閥門組合件應(yīng)具有防爆和防火結(jié)構(gòu)。

4、在低溫下工作的閥門組合件無法潤滑，所以需要采取結(jié)構(gòu)措施，以防止摩擦件擦傷。

5、閥門不應(yīng)成為低溫系統(tǒng)的一個顯著熱源。這是因為熱量的流入除降低熱效率外，如流入過多，還會使內(nèi)部流體急速蒸發(fā)，產(chǎn)生異常升壓，造成危險。

1. The valve shall be able to work for a long time under low temperature medium and ambient temperature.

2. Low temperature medium should not have harmful effect on handwheel operation and packing sealing performance.

3. The valve assembly directly contacting with low temperature medium shall have explosion-proof and fireproof structure.

4. The valve assembly working at low temperature cannot be lubricated, so structural measures should be taken to prevent abrasion of friction parts.

5. Valves should not be a significant source of heat for cryogenic systems. This is because the inflow of heat not only reduces the thermal efficiency, but also makes the internal fluid evaporate rapidly, resulting in abnormal pressure rise, causing danger.

三、進口液氧截止閥產(chǎn)品簡介：

低溫閥門著名品牌-德國LOCKE洛克生產(chǎn)的進口液氧截止閥的閥體和所有零部件均采用液氮進行深冷處理，完全避免使用過程中密封變形而導(dǎo)致泄露，具有開關(guān)靈活、密封可靠的特點。適用于低溫液體貯運設(shè)備的管理系統(tǒng)，也可用于其他低溫和深冷介質(zhì)的管理系統(tǒng)。

The valve body and all parts of the imported liquid oxygen globe valve produced by German locklock, a famous brand of low temperature valve, are cryogenic treated with liquid nitrogen to completely avoid leakage caused by seal deformation during use. It has the characteristics of flexible switch and reliable sealing. It is suitable for the management system of cryogenic liquid storage and transportation equipment, as well as other cryogenic and cryogenic media management systems.
